Best Answer

The individual electrons move slowly; the current moves quickly. Compare this to a water wave: the wave advances, but the individual water particles go back to their place. You should actually observe a water wave to confirm this. Check objects floating on the water. The wave is NOT a current of water.

You can also compare this to the following neat experiment with marbles: Put three (or more) marbles in a row, touching each other. Have one more marble bump into the row. The marble at the other end goes off - the other marbles stay in their place! The energy has been transferred from one marble to the next, but each of them (except the last one) stays in its place!

While slowly is a relative term, keep in mind that light travels at 186,000 miles per second, therefore by your perception, the light illuminates instantaneously.

What gives electrons there electricity?

Electrons don't have electricity they only posses energy, Electricity is defined as the flow of electrons! In conductors the flow of valence electrons are called Electricity! therefore inducing a current in it! generally the direction of flow the current is the opposite of the direction of flow of electrons(D.C)!


Where do electrons originate that flow down?

There are electrons in every atom, and every part of an electric circuit is made up of atoms (or charged atoms, which are known as ions). The electrons actually move very slowly around the circuit, going from atom to atom. However, the effect which causes them to do this travels very fast (at the speed of light) around the circuit. This effect is caused by the source of what is known as electromotive force - the battery, or power supply.

Why do electric circuits need to use conductors?

Without conductors, electrons do not flow where you want them to flow. An electrical circuit is a flow of electrons.
